As I could determine from the archive, the `id` function of XPath only

This sounds strange, since XML schema is a superset of DTD.
Ah, that's brand new to me, care to provide a normative proof of this ?
More seriously, no XSD is not an extension of DTD it's a completely
separate validation step, not part of parsing.
Is there are reason, why XML schema does not work with `id`?
Depends on your application. But basic XPath does not require or
depend on validation, just loading of DTDs to get attribute type. That's
not generally doable with XSD,
